That has led to reported interest from both Barcelona and La Liga winners Atletico, who are in the market for a new striker after seeing Diego Costa, David Villa and Adrian Lopez leave the club this summer.

Jose Callejon joined Napoli from Real Madrid in 2013.

According to Callejon, Atletico tabled a bid in excess of 25million euros and although the former Espanyol man would never rule out a return to Madrid, he is happy to remain with the Partenopei.
